The launch of a SpaceX rocket may be visible across the Southeast and Mid-Atlantic on Tuesday evening -- as the rocket ascends high enough to be seen by distant skywatchers. The launch time window is set for 6:07 to 7:07 p.m.

You can monitor SpaceX's live video streams here, and then allow a few minutes before glancing to the east-southeast. The stream will begin approximately 15 minutes before liftoff.

The rocket, which will take off from Cape Canaveral, Florida, is transporting to orbit satellites owned by the company Maxar.

Assuming the launch happens as planned -- though it can always be delayed or scrubbed -- the rocket will produce minimal natural light of its own. But it will climb so high in the atmosphere that its exhaust will catch sunlight long after the sun has set at ground level. That's why we'll be able to see the rocket's "jellyfish cloud."

The rocket will also inject moisture into the mesosphere, or third layer of the atmosphere, some 50 miles above the ground. There's very little moisture up there otherwise. The moisture added by the rocket might form "noctilucent clouds," which occur when moisture freezes onto small particulates of meteor smoke.

They're called "noctilucent clouds" because they glow in the dark (hence "lucent," which is derived from the Latin word for light, and "nocti," which comes from the word "night").

Austin DeSisto, a journalism student at the University of Maryland who enjoys astrophotography, has witnessed a Falcon 9 launch from D.C. before. He was able to spot it with the naked eye even from the National Mall.

"You don't really need dark skies," he said. "I saw it literally right by the Capitol. Which has streetlamps, bright lights, building lights, you know. So you don't need these dark-sky spots, like you would for, you know, aurora or some other phenomenon."
